Blueprints and elevation info to 3D model (SketchUp) - repost

I need some blueprints and elevation documents converted into a 3D model in Google Sketchup. The model should be well-built with logical grouping and no duplicate geometry. This model is going to be used in a game engine so low polygon counts and modelling efficiency are important considerations. We will handle texturing - that is not part of this job. Only bidders who can provide sketchup files of previous work (along with blueprints if possible) will be considered. It is a fairly large building - the building is approx. this scale: [login to view URL] This is an example of the interior detail required: [login to view URL]
